How it works. The ultrasonic vibrating screen is composed of a vibrator, a screen, an ultrasonic generator and a control system. When the ultrasonic generator is working, the ultrasonic waves are transmitted to the screen through the vibrator, so that the screen produces high-frequency vibration.

In short, as an advanced screening equipment, ultrasonic vibrating screen has an efficient, fine and stable screening effect, and has been widely used in various industries. Whether it is the food, chemical, pharmaceutical or metallurgical industries, ultrasonic vibrating screens can provide enterprises with high-quality screening solutions.
Screen material. The screen material of the fine screening machine is one of the important factors that determine its performance and application range. Different screen materials can meet the needs of different industries, such as chemical, food, pharmaceutical, petroleum, etc. Here are some common screen materials:
Wire braided mesh: Wire braided mesh is one of the most commonly used screen materials. It has the advantages of high temperature resistance, corrosion resistance, wear resistance, etc., and is suitable for dealing with high temperature and corrosive materials.

According to different material characteristics and screening requirements, selecting suitable screen materials can improve screening efficiency and product quality. At the same time, the selection of screen materials also needs to consider factors such as cost, service life and maintenance. Therefore, when choosing a screen material, various factors need to be considered comprehensively to meet the needs of different industries.
Mesh size. The mesh size of the fine screening machine is one of the important factors that determine the screening effect. The mesh size refers to the size of the holes on the screen and is usually expressed in millimeters. Different application areas and screening requirements require different mesh sizes.
When selecting the mesh size, the particle size distribution of the material and the screening target need to be considered. If the size of the sieve hole is too small, it will cause the material to fail to pass through the screen, which will affect the screening effect; If the mesh size is too large, it will make it too easy for the material to pass through the screen and not be able to achieve fine screening. Therefore, choosing the right mesh size is essential to achieve the desired screening results.
In some fine screens, the mesh size can be adjusted as required. This allows flexible adjustment to different materials and screening requirements for optimal screening results.
In practical applications, the commonly used mesh size range is 01mm to 100mm. The specific selection of screen hole size should be determined according to the characteristics of the material, the screening target and the production requirements. Generally speaking, for the screening of fine powders, the mesh size is smaller, while for materials with larger particles, the mesh size is larger.
In addition, the selection of the mesh size should also take into account the characteristics and durability of the screen material. Different screen materials have different wear and corrosion resistance, so when choosing the mesh size, the suitability and service life of the screen material also need to be considered.
In conclusion, choosing the right mesh size is one of the key factors to ensure the proper operation of the fine screen and the optimal screening results. According to the characteristics of the material and the screening requirements, the reasonable selection of the sieve hole size can improve the screening efficiency and product quality, and meet the screening needs of different industries.
Sieve length. The length of the screen surface of the fine screen machine refers to the length of the effective screening area of the screen. The length of the screen surface is an important parameter of the fine screening machine, which directly affects the screening effect and production capacity.
When choosing a fine screening machine, the length of the screen surface needs to be determined according to the characteristics of the material and the screening requirements. Generally speaking, the longer the sieve length, the better the screening effect, but at the same time, it also increases the volume and power consumption of the equipment. Therefore, in practical application, it is necessary to make a reasonable choice according to the specific situation.
The selection of the screen length also needs to take into account the particle size distribution and humidity of the material. For materials with a more uniform particle size distribution, a longer screen length can better achieve fine screening. For materials with uneven particle size distribution, a shorter screen length can better achieve fast screening. In addition, for materials with high humidity, a longer screen length can increase the screening area and improve the screening efficiency.
In practice, it is also necessary to determine the length of the sieve surface according to the output requirements of the material and the production capacity of the equipment. If the material output is large, a longer screen length can be selected to improve production efficiency. However, if the material output is small, a shorter screen length can be selected to save energy and reduce the equipment footprint.
In short, the length of the screen surface is an important parameter that affects the screening effect and production capacity of the fine screening machine. When selecting the length of the screen surface, it is necessary to comprehensively consider the characteristics of the material, the screening requirements, the output requirements and the production capacity of the equipment to achieve the best screening effect and economic benefits.
